| Subject: | tests may fail on Win32 when IPC::Run is installed, Archive::Tar is not, and tar.exe exists |
If (on win32, perl5.8.8) IPC::Run is installed and Archive::Tar is not
installed, *and* you have some version of 'gzip.exe' and 'tar.exe' on
your path (from MKS, cygwin, or msys/mingw), then the tests may fail
exactly like this cpan-testers report:
http://www.nntp.perl.org/group/perl.cpan.testers/2007/12/msg832293.html
This is the test debug output:
# Older versions of Archive::Zip may cause File::Spec warnings
# See bug #19713 in rt.cpan.org. It is safe to ignore them
ok 1 - use Archive::Extract;
# IPC::Run enabled: 1
# IPC::Run available: 1
# IPC::Run vesion: 0.80
# IPC::Open3 enabled: 1
# IPC::Open3 available: 1
# IPC::Open3 vesion: 1.02

In this case, the gzip.exe on my path was from MKS, and the tar was from
msys. gzip was outputing an errant extra error message.
Installing Archive::Tar before testing fixes this problem.
